well i just noticed this but when im on a web page or anything that scrolls my mouse does not scroll down but it will scroll up so do u think its broken or what.....?
 
I had the same problem. Like MD said, it was caused by gunk getting in the ball. You scroll down a lot more than up, so it gets dirty easier. Just clean it out, and you'll be good to go once again.
 
finaly got it thanks it took me like forever to find a shim and the rightsize screwdriver also i dropped the little roller things but it payed off it works
